LEATHER-BEADING DE VICE.

SPECIFICATION forming part of Letters Patent No. 761,696, dated June '7, 1904.

Application filed October 10, 1903.

To all 1077/0777, it party concern.-

Be it known that we, JOHN G. MOCARTER and AARON WALDo Rooxwoon, of Hydepark, in the county of Norfolk and State of Massachusetts,have invented certain new and useful Improvements in Leather-Beading Devices, of which the following is a specification.

This invention has for its object to provide means for forming a beaded or finished edge on a strip of leather, the finished edge of the strip being intendedto be exposed at the edge or edges of an article, such as the ankle portion of a laced or buttoned boot or shoe, to impart a neat and ornamental appearance to the article.

The invention consists in the improvements whichwe will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective View of a leather-beading tool embodying our invention. Fig. 2 represents an edge view of the same. Figs. 3 and trep resent opposite end elevations. Fig. 5 represents a side view of a leather strip to be beaded, the strip being shown as it appears before being subjected to the beading-tool. Fig. 6 represents, partly in elevation and partly in section, the chief portions of an ornamental machine of which the above-mentioned tool forms a part, the leather strip being shown in its passage through the machine. Fig. 7 represents a side view of the strip after it has been beaded. Fig. 8 represents a plan view of the parts shown in Fig. 6. Fig. 9 represents a section on line 9 9 of Fig. 6 looking toward the left. Fig. 10 represents a section on line 10 10 of Fig. 9. 4 e

The same reference characters indicate the same parts in all the figures.

In the drawings, a represents a beadingtool, which is preferably composed .of a block of metal shaped substantially as shown in Figs. 1, 2, 3, and 4:, one edge of the block having a longitudinal groove (0. The form of said groove in cross-section is such that it will be produced by drilling a circular hole through the tool a from end to end and then grinding Serial No. 176,485. (No model.)

off one edge of the tool to form a face 2, intersecting the circular orifice, but located at one side of the center thereof. The groove (0' therefore has a month which is somewhat contracted on the face 2, the widest portion of the groove being within said face, as shown in Fig. 9. Moreover, the inner surface of the groove, and particularly the rear wall thereof, which performs the operation of burnishing, is straight for a sufficient length to enable said wall to form and burnish the edge of the strip during a single pass of the strip through the groove. One end of the groove is widened, as shown at (4 and the said widened portion is also deepened by a rearward curvature of the back of the groove, as shown at cf, Fig. 10.

t represents a strip of leather or other like material, the thickness of the stripbeing preferably somewhat greater than the width of the contracted mouth of the groove a, so that the sides of the strip bear closely against the opposite edges of the said contracted mouth and are slightly compressed or indented thereby. Theenlarged endportion a of the groove permits the strip to be readily inserted in the groove.

0 0 represent a pair of feed-rolls, which are positively rotated in the directions indicated by the arrows marked thereon in Fig. 6 and are arranged to grasp the strip 5 between their opposed surfaces, the rolls exerting sufiicient pressure on the strip to feed it endwise. The tool a is fixed to a bed or table d, which occupies a fixed relation to the axes of the feedrolls 0 c, the arrangement being such that the groove (0 is slightly above the upper surface of the table and inline with the nip above the feed-rolls, all as indicated in Fig. 6.

When a strip 6 is introduced into the groove (4 and grasped by the feed-rolls c c, the rotation of said rolls causes them to pull the strip through the groove. The tool a is heated by any suitable means, (not shown,) and the edge of the strip a is or may be treated with a suitable burnishing-ink or other composition which will cooperate with the heated tool in producing a lustrous finish on the edge of the strip. As the strip is drawn through the groove a its inner edge is upset or rounded by contact with the heated wall of the groove, so that the edge of the strip is beaded and at the same time burnished. The form imparted to the edge or edges of the strip by this operation is clearly shown in Fig. 9. The contraction of the mouth of the groove is an important feature, since this contraction causes the acuteangled edges of the groove to engage the sides of the strip and prevent the strip from being crowded edgewise outwardly from the groove. The material of the strip between the mouth and back of the groove is therefore held firmly in contact with the forming and burnishing Wall of the groove while being moved therein, so that a single pass of the strip through the groove is sufficient to form and burnish the edge of the strip.

We claim 1. A leather beading and burnishing tool having a longitudinal groove contracted at its mouth to form acute-angled edges formed to engage opposite sides of a strip of leather and hold the edge of the strip in contact with the forming and burnishing wall of the groove, the said groove being enlarged at its receiving end, and having the remainder of its walls substantially parallel.

2. A leather beading and burnishing mechanism, comprising a fixed beading-tool having a longitudinal groove contracted at itsmouth to form acute-angled edges formed to engage opposite sides of a strip, and means for teeding a strip through said groove.

In testimony whereof we have aliixed our signatures in presence of two witnesses.
